About Us

KPH To MPH Speedometer Conversion

We provide speedo converters & delimiters for imported Japanese, and some European,cars, that do not have an MPH speedometer display. For Japanese cars that are limited to 112 mph the conversion can often remove the speed restriction by way of a delimiter.

You can check out your make and model on this site to identify the converter you need. Each converter/delimiter comes with it’s own instruction set, downloadable from this site, and with one click of your mouse a speedo converter/delimiter can be ordered at exceptional value, postage included.

If you have any questions or queries please contact us via email or telephone to Discuss your particular vehicle’s requirements.

KPH - MPH Motorcycle Converters

This mechanical Kilometre converter converts the speedometer and milometer from kilometres to Miles per hour. This clever device connects directly between your Speedo cable and your speedometer.

It connects directly onto your speedometer and your existing cable then fits back onto the converter.
Before you purchase one of these be sure that you have a mechanical Speedo and not an electronic version , this can be checked by looking at the wheel to make sure you have a cable not a wire coming up from the wheel to the Speedo, you will also need to make sure that you have enough room under you Speedo to fit the converter.

Speedo Converters / Delimiters

Japanese performance vehicles imported from Japan will be road speed restricted to approximately 112 MPH. While this restriction does not affect driving on public roads, off-road use on specialised tracks, race circuits and German Autobahns is obviously impaired. More click here...

SVA delimiters can remove this restriction. In most cases, the same unit used to convert the speedometer to MPH, can also enable de-limiting.


Radio Band Expanders

The Radio Band Expander enables the original equipment radio in Japanese import cars to receive UK radio transmissions. It achieves this by shifting the UK transmission frequencies into the band that the Japanese radio will detect.

The cars catered for on this website including Honda, Isuzu, Lexus, Mazda, Mitsubishi, Nissan, Subaru and Toyota’s sometimes come with their original radio. Japanese radios have a bandwidth of 14MHz (76-90MHz) compared to the UK bandwidth of 20MHz (88-108MHz), hence a certain band of frequencies will be lost when the car is in the UK. SVA supply radio band expanders which allow the original radio equipment to pick up UK radio stations.
